So I have a 85 6.9L IDI Can I run B20? What can I run?
I don't have to change anything on the truck at all? Just carry a spare fule filter?
In 94' the US went to low sulfur diesel, and with that came different engine requirements (mostly updated emissions) one of the things that was changed were the fuel lines. Prior to 94' (give or take) diesel pickups, cars, vans ect... used fuel lines with a high rubber content, and bio diesel has been known to eat or deteriorate them over time. I've heard a million different stories, but most "experts" say a blend like B20 or lower has very little effect on them
. If a possible leaky fuel line in the future is too much to risk than you can swap your factory ones for a set of Viton lines that are Bio-proof. As far as your fuel filter goes all you have to do is change it after your first or second tankfull (mabey once more after that just to be on the safe side), and you should be back to your normal filter change schedule.
Other cons- Poor cold weather performance, and basically flushing the crap (if any?)out of your tank into your fuel filter.
FYI I have an IDI Chevrolet pickup, and like I said have ran B100 for months on end. I really like the way my truck behaved while using it. I feel like the Bio diesel really gave my fuel system the lubricating effect that it needs, and was designed for aposed to low sulfur #2. I think that the decision to start using ultra low sulfer in the US is going to be a big problem for people like us if it becomes the domonant source of fuel :sick:, and Bio might become more popular than it already is. Just some thoughts
